Greenhouse bulbs. Offset bulbs; old bulb* 

 are generally obtained from Italy every year, and 

 are planted in rich, sandy loam ; and when growth 

 has fairly commenced, they get the advantage of 

 a slight hotbed to forward them (but the bulb, 

 and not the top, should be kept warm), before 

 getting them ready for rooms or greenhouses.

Half-hardy herbaceous perennial. Division and 

 cuttings of the young shoots in spring, in sandy 

 soil; the protection of a cold frame, or some 

 analagous place, in winter.

POLYA'NTHUS. This is a variety, but 

 a very permanent one, of the common 

 Primrose (Pri'mula vulya'ris). There 

 are many varieties, and their excellence 

 as florists' flowers may be determined by 

 the following rules: 



The Pip. I. This should be perfectly 

 flat and round, slightly scolloped on the 

 edge, and three quarters of an inch in 

 diameter. 



2. It should be divided in (five or) 

 six places, apparently forming (five or) 

 six flower-leaves, each indented in the 

 centre to make it a kind of heart-shaped 

 end; but the indentations must not 

 reach the yellow eye. 



3. The indenture in the centre of the 

 apparent flower-leaves should be exactly 

 the same depth as the indenture formed 

 by the join of these flower-leaves, so that 

 it should not be known, by the form of 

 the flower, which is the actual division 

 and which is the indenture ; in other 

 words, which is the side and which the 

 centre of the flower-leaf; and all the 

 indentures should be as slight as possible, 

 to preserve the character. 



4. The flower should be divided thus : 

 the yellow tube in the centre being 

 measured, the yellow eye, round the 

 tube, should be the same width as its 

 diameter; and the ground colour of the 

 flower should be the same width ; or 

 draw with the compasses, opened to a 

 sixteenth of an inch apart, a circle for 

 the tube or centre, open them to three- 

 sixteenths, and draw another circle for 

 the eye, then open them further to five- 

 sixteenths, and draw a third circle for
